I can't trust my friends

I honestly feel like I can't even trust my friends enough to vent to them. My "bff" Is really selfish to the point I started to believe she had narcissistic personality disorder. Even If I tried she would just make It about herself and forget I am the one who came to her for help. My other friend literally uses my weak moments where he helped me feel better as If they were thropies. He doesn't even ask for consent and just tells random people about what I told them as If It was a joke and without my permission. Lastly, my other "friend, " which I am not sure If he even considers me a friend, only follow around the other friend I talked about and doesn't care about me, he's too focused talking 24/7 to him, and It's like he doesn't have a personality of his own. The rest of my friend are either not too close to me for me to feel comfortable talking about my problems to them or just not the right people to vent to.
